CNN: 4 ways we're still fighting the Civil War

April 11, 2011- He stood 5-foot-8 and weighed 145 pounds. His face was gaunt and sunburned. Ticks, fleas and lice covered his body.

Before battle, his lips would quiver and his body went numb. When the shooting started, some of his comrades burst into maniacal laughter. Others bit the throat and ears of their enemy. And some were shattered by shells so powerful that tufts of their hair stuck to rocks and trees.

Take a tour of a Civil War battlefield today, and it's difficult to connect the terrifying experience of an average Civil War soldier -- described above from various historical accounts -- with the tranquil historic sites where we now snap pictures today.

But you don't have to tour a battlefield to understand the Civil War. Look at today's headlines. As the nation commemorates the 150th anniversary of its deadliest war this week, some historians say we're still fighting over some of the same issues that fueled the Civil War.

"There are all of these weird parallels," says Stephanie McCurry, author of "Confederate Reckoning," a new book that examines why Southerners seceded and its effect on Southern women and slaves.

"When you hear charges today that the federal government is overreaching, and the idea that the Constitution recognized us as a league of sovereign states -- these were all part of the secessionist charges in 1860," she says.

These "weird parallels" go beyond the familiar debates over what caused the war, slavery or states' rights. They extend to issues that seem to have nothing to do with the Civil War.

The shutdown of the federal government, war in Libya, the furor over the new health care law and Guantanamo Bay -- all have tentacles that reach back to the Civil War, historians say.

They point to four parallels:

The disappearance of the political center

If you think the culture wars are heated now, check out mid-19th century America. The Civil War took place during a period of pervasive piety when both North and South demonized one another with self-righteous, biblical language, one historian says.

The war erupted not long after the "Second Great Awakening" sparked a national religious revival. Reform movements spread across the country. Thousands of Americans repented of their sins at frontier campfire meetings and readied themselves for the Second Coming.

They got war instead. Their moral certitude helped make it happen, says David Goldfield, author of "America Aflame," a new book that examines evangelical Christianity's impact on the war.

Goldfield says evangelical Christianity "poisoned the political process" because the American system of government depends on compromise and moderation, and evangelical religion abhors both because "how do you compromise with sin."

"By transforming political issues into moral causes, you raise the stakes of the conflict and you tend to demonize your opponents," Goldfield says.
